A iioor 1 is huilt upon joists 2 and a rectangular opening 3 Vis madethrough the ioor 1 between two joists. An outer shell l 4 is straight upand down, rectangular in plan, and has an out-turned flange 5 at itsupper end all the way around so that the shell fits closely in the hole3 .and the .flange rests upon'the floor 1 aroundthe hole.. The shell 4is preferably formed `of heavy galvanized iron. `A layer of asbestospaper 6 is pasted to the outer face of the outer shell 4.

A gas feed pipe '7 has a union 8 lupon its end. A T 9 is connected tothe other end of the union from the pipey 7. Anipple 10 ex'- tendsoutwardly from the T 9 and a cap 11 is mounted upon the lower lend ofthe nipple 10 to make a drip ot. A pipe 12 extends upwardly from the I 9insideA of one wall of the outer shell 4.

"A double gas cock fitting 13 is connected to the upper end of the vpipe12. The double gas cock fitting 13 consists of a female nipple 14screwed upon the end of the pipe 12, a gas cock construction 15extending one way from' the nipple 14, and 'a as cock construction 16extending the ot er way from the nipple 14, and ears 17 through' whichscrews 18 are inserted to secure the fitting against the inner face oflthe outer shell 4 directly below its upper edge. Movable valve members19 and 20 havesockets with openings to receive a key 21 so that the keymay be inserted into either one of rthe valves and the valve operatedand the f key removed.

A reinforcing plate 22 is secured against the inner face of the outershell 4 byy rivets' 23 and the screws 18 are inserted through vthevea'rs 17 and tapped into the plate A main supply pipe 24 is connectedto the 'l valve construction 16 and extends down-4 wardly to mainburners 25 and 26 and a pilot light pipe 27 is connected to the valveconstruction 15 and extends downwardly to a pilot burner 28 so that byplacing the key 21 in the valve 19 the pilot burner may be controlledand so that by placing thel key 21 in the valve 20 the main burners maybe controlled.

A bottom 29 is inserted upwardly into the lower end of the outer shell 4and secured in place by bolts 30. In assembling the parts the bottom 29is placed in positionbefore the pipes 20, 24 and 27 are. placed inposition. The details of the bottom 29 are as follows: The bottom 29 ispreferably a casting and comprises a rectangularl flat plate 31, and aflange 32 extending downwardly all the way around from the edge of theplate 31. A rectangular opening 33 iS formed through the plate 31, therebeing a rib 34 extending upwardly all the 'way around the opening 33 ashort distance outside of the edge of the opening, thereby forming aledge 35 all the way around the edgev of the opening. A wall 36 extendsdownwardly from the plate 31 in vertical alinement ith. the rib 34 toform a -housing around thevburners 25, 26, and 28, said housing beingopen atthe bottom to -provide a free circulation of air upwardly throughthe housing around the burners to the combustion chamber. A circularopening 37 is formed through the` plate 31 at one end of the opening'33,An annular rib 38 extends upwardly from the plate 31 around the opening37 a short distance outside of the e ge of the plate to form a ledge 39.Bolt holes 40, 41, 42 and 43 are formed throughv the plate 31.

The details of a radiator base44 shown in Fig. 6 includes the parts v45to 74 and are as follows: Thebase 44 is an integral casting and has arectangular housing 45 open at the top and bottom and fitting upon theledge 35. A circular housing 46 is open at-the top and bottom and fitsupon the ledge 39 and a web 47 connects the circular housing 46 to therectangular housing 45. A iue nipple 48 extends horizontally from thehousing 46 at the opposite side from the housing 45. VFlue bottoms 49,50 and 51 extend horizontally outwardly from the upper edge of the wall52 of the housing 45 and similar flue bottoms 53, 54 and 'extendhorizontally outwardly from the upper edge of a wall 56 of the housing45. A flue bottom 57 extends from the upper edge of a wall 58 of thehousing 45 over the web 47 and Hue bottoms 59 and 60 extend outwardlyfrom the up er end ofthe housing 46 in line with the ue bottoms 49,-

4 50 and 51-and flue bottomsl and 62 extend horizontally outwardly fromthe up er end of the housing` 46 inline -with the ue bottoms 53, 54- and55. The flue bottoms 49, 50, 51, 59, 6o, 62, 61, 55, 54 and 53 areevenly -spaced apart thereby forming air passages 63, 64, and 66 oneside of the casting and similar air passa es 67, 68, 69 and 70 on theother side o the casting, Flanges 71 and 72 extend upwardly from theupper edge of an end wall 73'of the housing 45, thereby forming achannel 74 55 between the flanges. The anges 71 and 72 are continuousextending upwardly along the edges of the flue bottom 49, then along theedge of the wall 52, then along the outer edge of the floor bottom 50,and so on all the way around the casting.

The details of the central radiating element 75 as shown in Fig. 5 areas follows:

Y A radiating element 75 is made of sheet metal and vpreferablyvconsists of two vmating pieces 76 and 77. The main part of the piece 76is bent in and out' to form hot air lues 78, 7 9, 80, 81 and 82 fittingin the channel 74 around the flue bottoms 53, 54, 55, 61 and 62, andforming channel shaped air passagesl 83 between the hot air fluesin linewith the air passages 67, 68, 69 and 70, and

the air passages 63, 64, 65 and 66.

A partition 90 consists of a flat plate in Serted in the hot air flues81 and 87 against the walls of the air passages 83 and 89 which arebetween the hot air flues 80 and 81 and 86 and 87 and held in place bybolts or rivets 91. The partition is cut short and extends from thebottom of the radiating element 75 nearly to the top thereby leaving ahot air passage 92 over the top of the partition. The/pieces 76 and 77are connected together by Vertical seams 93 and 94.

The details of the top plate 95 of the radiator shown in lFig. 4 are asfollows: A top plate 95 isa castlng and consists of a main ody 96 havinnotches 97 and 98 extending from'its side e ges, an opening 99 extendingthrough one end and surrounded by an upwardly projecting annular ring100 and bolt holes'101, 102, 103 and 104 formed through its corners. Thenotches 97 are in line with the air passages 89 in the radiating element75 and the air passages 63, 64, 65 and 66 in the casting 44, andprojections between the notches 97 Vare in line with the hot airiiues-'84, 85, 86, 87 and 88 and in line with the' flue bottoms 49, 50,51, 59 and 60. In a like manner projections 106 between the notches 98are in line with the hot air lues 78, 79, 80, 81 and 82 and in line withthe flue bottoms 53, 54, 55, 61 and 62, and the bolt holes 101, 102,103, and 104 'are in line with the bolt holes 40, 41, 42- and 43 in thecasting 29. A lower face 107 of the top plate 95 is practically a mateto the upper face of the casting 44. Flanges 108 and 109 extenddownwardly all the way around the edge of the casting 95 and form achannel 110 in which the upper edge of the radiating element 75 its. Thelower edge of the radiating element 75 ts in the channel 74 in thecasting 44.

Stove bolts 111 are inserted downwardly through the bolt holes 101, 102,103 and 104 and through the bolt holes 40, 41, 42 and 43 and nuts areplaced upon the lower ends of the bolts to hold the outer shell bottom29, the base 44, theradiating element 75 and the top plate 95 securelytogether.

A cap 112 fits upon the annular ring 100 and thecap 112 consists of aninner member 113 fitting within the annular rin 100; an outer member 114fitting outside 0 the ring 100; a mica plate 115 fitting between themembers 113 and 114; and a andle 116, all the parts being securedtogether by bolts 117. The member 113 is L-shaped in cross section andhas a flat upper face upon which the mica plate 115 rests. The member114 has a flat lower face fitting upon the mica plate 115-and extendsdownwardly and outwardly to form a channel 118 to receive the ring 100.

A register frame 119 fits upon the floor 1 over the flange 5 and ears120 extend inwardly from the frame and screws 121 are inserteddownwardly through the ears and tapped into brackets 122 secured to theinner face of the outer shell 4. Agrate 123 extends inwardly from theframe 119 all the way around to make a rectangular opening 124, therebeing a ledgeA 125 extending inwardly all the way around from the oe-ning 124. An intermediate casing 126 is ormed of sheet metal and theupper end of the casing 126 is reduced in size and inserted upwardlythrough the opening surrounded by the ledge 125 andthe upper edge of thecasing is turned outwardly to form a flange 127 fitting upon the ledge125 so as to support the casing 126. The casing 126 extends downwardlyto a point half way between the top and the bottom of the casting 44,thereby forming a cold air passage 128 leading downwardly through thegrate 123 between the outer shell 4 and the intermediate cas-- upwardlyoutside of the radiator 75 and inl side of the intermediate casing 126.A flue 130 is attached to the nipple 48 and extends outwardly throughthe outer shell 4.and up'- wardly to any desired position. A registergrate 131 is loosely mounted within the grate 123 and upon the flange127 to cover the radiator so that when desired the register 131 may beremoved and the cap 112 removed to light the pilot 28.

For the purpose of lightin the pilot 28 I employ7 a match holder 132ormed of wire comprising a handle 133, a lon stem 134 and a coil 135. Alighted matc 136 may be pressedbetween the strands of the coil 135, thehandle 133 manually grasped and. the match holder inserted downwardlythrough the cap hole 99, then the key 21 may be operated to turn on thegas to the pilot '28. As soon as the pilot 28 ignites the cap 112 may-bereplaced and the grate 131 replaced, then the key 21 may be operated toturn on the gas through the pipe 24 to the burners 25 and 26. The freshair will pass upwardly around the burners within the wall 36, then thehot air and products of combustion will pass upwardly through thehousing 45 and upwardly through the radiator 75 above the housing 45 andthrough the hot air passage 92 over the top of the partition 90 anddownwardly through. the radiator `to the housing 46, and then outwardlythrough the nipple 48 and through the flue 130. Fresh air will passupwardly 'through the opening 37 to the ousingf46 and mix with theproducts ofv casting'44 and will pass upwardly inside of the casing 126and through the passage 129 and around the radiating element and topplate 95 and then the hot fresh air will pass upwardly through theregister 131 to warm the room. By removing. the screws 121 the grate 123carrying the intermediate casing 126 and the grate 131 can be removedvto provide access to the interior of the outer shell 4 and the furnacecan be thoroughly cleaned from the floor 1 and the parts 19 and 20 canbe oiled and repaired.
